Discovery of CO Clouds Associated with the X-ray Jets of SS 433: Evidence for Shock-Cloud Interaction Enhancing Nonthermal X-ray Emission
Haruka Sakemi, Hidetoshi Sano, Yasuo Fukui +7
We report the first identification of molecular clumps directly associated with the re-brightening regions of the large-scale X-ray jets of SS 433, based on CO ( = 1--0)…

RAMBO I: Project introduction and first results with uGMRT
Z. Keszthelyi, K. Kurahara, Y. Iwata +4
Magnetic hot stars can emit both coherent and incoherent non-thermal radio emission. Understanding the nature of these emissions and their connection to stellar rotation and magnet…
